So pure speed is the only barometer for a thrill ride? C'mon Bob, a thrill ride expert like yourself should know that's not the case. Its not how fast you are going, its how fast you FEEL like you are going, plus all of the other factors in the ride.
If its speed alone, what is Space Mountain and Big Thunder Mountain Railroad?
Despite how it impacts YOU, or even ME, most people consider TT a thrill ride. But regardless, it draws big lines and has plenty of merchandise, so according to your logic that's what will work for Disney. But Epcot's attendance continues to plummet. It had the biggest percentage drop of the four WDW parks for the 2nd year in a row, despite having the most significant recent attraction added.
It could be done in a Disney manner, IMHO
Ohana, I agree that your version is certain more "Disney-like" than the drag racing version. And if they were going to do it, they should do it with that kind of idea (or something else completely different, but the point is, with a STORY, SHOW, and THEMEING).
However, its just not the BEST use of Disney's investment at this time. They need to find ways to provide STORY, SHOW, etc in ways that appeal to everyone in the family. Think something that has all the show elements you described, and instead uses any combination of simulators, 3-D images, animatronics, WHATEVER, and still makes you say WOW!
THAT'S what Disney used to do best, but are now abandoning.
Space Mountain, The Matterhorn, Big Thunder, Tower of Terror, Splash Mountain, all great! But now, that's the only kind of attraction Disney wants to give us, except for 3d movies and pure kiddie rides. And the STORY and SHOW is becoming a smaller and smaller part of these rides because it costs money, and because many of the people who are looking for these types of rides don't care as much about the story and show.
The problem is that slowly but surely, the core Disney audience is getting less and less from Disney to be excited about.
